LOOSE-LEAF BINDER.

To all whom it may concern:

Be it known that I, GLEN SwI'rzER, a c1t1- zen of the United States, residing at Macon, in the county of Macon and State of Missouri, haveinvented certain new and useful Improvements in Loose-Leaf Binders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This'invention relates to loose leaf'binders and'more particularly to loose lea-f check covers or binders. V w

The object of the invention is to provide a loose leaf binder, the posts of which are adjustable to engage leaves having holes spaced different distances apart or at differentplaces. 1

Another object is to provide a binder of this character especially designed as a check binder and which is so constructed that there will be no covering over the stub end of the checks at the back. 7

wWith these and other objects in view, the

invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 represents an edge view taken from one end of this improved binder and shown inoperative position; Fig. 2 is a transverse section taken on the line 2-2 of Fig. '1; Fig 3 is a longitudinal section taken on the line 3-3 of Fig. 2; Fig. 4: 'is a horizontal section taken on the line 4l of Fig.;3; Fig. 5 isa plan view with one leaf or cover member of the binder removed, and Fig. 6 is a perspective view of the binder andthesheets to be disposed therein arranged in juxtapo- Specification of Letters Patent.

mediately of its ends forming leaves 4 and 5gwhich are spaced apart a suiiicient dis- .tance' to permit the heads of the poststo be described to move freely between them.

The leaf 5' is considerably longer than leaf 4 and overlaps the outer face of the rear end of the back land is secured thereto.

by riveting or. otherwise, while the narrower plate 4 has its free edge abutting against the rear edge of. the back 1, as is shown clearly in'Figs. 1 and 3. The plate a is disposed on the inner face of the back 1 and is arranged substantially flush" with the inner face thereof and is provided with --tionsthereof extending nearly'to the outer ends of said plates. These slots are de- 9 and 10 which are here shown provided with the usual disk like heads 11 with shanks 12 extending centrally fromone face thereofand threaded at their outer ends to receive. clamping nuts 13 which are prefer- Y ably milled on their edges to facilitate their turning. The heads of these posts are of slightly less diameter than the rounded openings 8 of the slots 6 and 7 to permit signed to receive the leaf supporting posts i V said heads to enter said openings 8 and to slipbetween the leaves 4 and 5 in the slots 6 and 7 sothat they may be adjusted at any desired point within the slots to adapt them to receive checks orother sheets le Which. are provided at their rear endswith apertures for the passage therethrough of the shanks of these posts; The other back 2 is shown of the same width and size as the back 1 and has a flexible hinge member15 secured to its rear end and-which is here shown composed ofa' leather strip of double if thickness and of the same width or slightly greater width than said back 2 so that the opposite edges thereof may befolded' over the. edges of said back and secured. -This strip 15 may be of any desired length and is provided near its'free edge witha pair of transversely extending alined slots 16 and 17. spaced apart at their inner ends and which are adapted to pass over and slidably receive the posts 9 and 10 to permit said sponding to the width of the leaf 4 of plate i 3. This clamping plate 18 is provided with longitudinally extending slots 19 and 20' spaced. apart at their inner ends and which are adapted to fit over and slidablv receive the posts 9 and 10 after said posts have been passed. through the, apertures in the checks or other sheets 1d which. are to. be clamped between, the backs 1 and 2, and through the slots 16. and 17 in strip. 15. of back 2., and when said parts have been so. disposed this plate 18 is engaged with the free ends of the posts and the nuts 18then screwed ontothe threaded ends of said posts into clamping engagement with the plate 18,, thereby forcing said plate downwardly on the checks 4 and securely binding them between the plates 18 and the rear end of back 1 so that said; backsl and 2 arethu's securely held together withv the sheets 14 clamped between them, The back 2 is designed asv av protective cover for the, outermost check or sheet 14 andmay be readily opened to, expose said sheet.

From the above description it is thought that the operation of the device will. be obvious) but a brief description of the assembling of the, parts will be, given below; to wit: When, it is desired to. assemble, the ac s. 1 and 2 and to mount. e een them checks or other sheets 1%,, the heads oi the studs. 9 and 10. are first. inserted in the rounded pertur s 8v at th i ne n s i h key hole slots 6 and 7 and. then moved into said slots the, desired distance to position them to receive the apertures in the checks or sheets which they are designed to, connect. After they have been so disposed, the. Cletice is ready to,.;receive the checks 14 which are engaged with the posts by threading the. apertur s h ein. nvth po t nd. af erth desir d umber o e k hav b en so ranged,, the, slotted leather hinge, 15 is en gaged with the; posts by passing them through the slots, 16, and 17 therein, Lhe clamping plate 18. is passed over the posts 9 and 1 0 with the, threaded ends.- of said posts P jecting l' s the ts ins id p t andthenut-s 18, are then secured to the ends of the posts and the parts. reliably clamped in operative position where they: will be. held until thenuts are loosened: and the parts disn cted-l. By S varranging these parts with the leather strip, 15 disposed above the outermost check lhfthe rear ends or stubs of the checks, will be uncovered as. shown in F gs l nd t adapt Saidstuds to project beyond the hack members 1 and 2. should the apertures therein be formed at points spaced mwardly from said rear edges such a distance as to cause these edges to project beyond the backs after the posts 9 and 10 have been inserted therein.
